To all whom it may concern:

Be it known that I, GEORGE W. BUCK, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Cement-Block Machines, of which the following is a specification.

This invention relates to improvements in cement block machines, adapted for use in forming cement blocks for buildings, and has for its object the production of a machine which will consist of few parts and which may be economically constructed, also to present an arrangement of parts whereby building blocks may be formed with a small outlay of labor; also the invention has reference to a means for producing a particular form for corner blocks and for bonding, found to be of advantage. i

The novel features of the invention are fully described herein, pointed out in the appended claims and illustrated in the drawings, wherein,

Figure 1 represents a, vertical front view of a cement block machine embodying my invention, showing the spreading-arms 33 in a released or drawn position. Fig. 2 is an end view of the parts shown in Fig. 1, the pallet being removed. Fig. 3 is an end view, being the end opposite that shown in Fig. 2, the door being closed and pallet re moved. Fig. 4: is a view similar to that shown in Fig. 3, except the door is shown opened. Fig.5 is a view somewhat similar to that shown in Fig. 1, the front part of the frame and pallet being removed to show use of one of the molds and to illustrate relative position of parts. Fig. 6 is a vertical end View of the machine, illustrating use of pallet and swinging pallet-arms or rock-lever. Figs. 7, 8, 9 and 10 are vertical side views of the molds employed, Fig.9 being the mold used for forming corner blocks. Figs. 11 and 12 are plan views of part of a wall built by use of the blocks shown, and illustrating alternate courses. Figs. 13,14 15 and 16 are side views of blocksmade by the herein described machinewhen used in con- .nection with the molds shown in Figs. 7, 8, 9 and 10. Fig. 17 is a plan View of my invention, arms 17 of the rock-levers being partly in section; also showing afragment of a mold. Fig. 18 is a detail relating to .Fig. 17., showing relative position of parts. Fig. 19 is a broken away, front view of a j part of the invention showing the spreadinggarms in an extended position. Fig. 20 is an ;end view of the parts shown in Fig. 19, ;looking to the left of that figure. F igf 21 ,is a front view of the L-shaped pallet-sustaining plate 22, to clearly show apertures therein, to admit the lugs upon the pallet. Fig. 22 is a perspective View of the L-shaped Z pallet and lugs thereon. Fig. 23 is a per- ;fspective view of a rectangularly formed ipallet, and lugs thereon, this pallet being used in connection with molds for forming gthe building blocks of lesser lengths.

I Referring now to the drawings for a more fpartioular description, numeral 1 indicates =a cement block machine, and in order that ithe parts for forming the blocks may be supported operatively and conveniently, I conistruct a frame work, consisting of the hori- Ezontally-disposed supporting-arms 2 and 3, sustained by legs 4, 5, 6 and 7 legs 5 and 7 are extended upward to form arms 8 and 9, these arms being disposed at a right angle :to supporting-arms 2 and 3, and, preferably, ;I employ braces 10 and 11 for connecting the legs at the ends of the machine, and in order that the parts may be sustained securely, I employ cross-pieces 12 and 13, which con-' inect the rear legs, the front legs near their lower ends being connected-by rod 14:. It is intended by this construction to furnish an adequate support for the parts during-the process of making the blocks, and it is preferred generally to cast the legs and supporting-arms integral for use upon each end of {the machine. i

. I construct rock-levers 15 and 16, each having the arms 17 and 18, these'arms being disjposed at substantially a right angle for each rock-lever, the latter being pivotally mounted in the frame at 19, as by means of rod 20. ;Upon arms 18 is rigidly secured the rectanigularly-formed base-plate 21, and upon arms 17 is rigidly secured the L-shaped pallet-sustaining plate 22; plates 21 and 22 are, there'- fore, disposed at a right angle with reference to each other; and upon arms 8 and 9 of the frame is rigidly and vertically secured the L-shaped molding-plate 23. Plates 22 and 23 are uniform in extent and shape, and

when the parts are in normal position these plates are parallel with reference to each other, and each is formed as a rectangular plate a; (Fig. 21.),having alateral projection 5 formed at one of its ends and disposed within the plane of the rectangular portion; molding-plate 23 is stationary upon the frame, but plate 22 may have a swinging movement with arms 17. i

The normal position of rock-levers 15 and 16 are as shown in Figs. 1, 2, 3 and 4, and the parts thus far described furnish a housing-space 24 (Fig. 4.) within which are placed any one of the molds hereafter described, the latter resting upon base-plate 21, this base-plate being supported upon arms 2 and 3.

Reference to Figs. 7, 8, 9 and 10 shows that, each of molds 25, 2G, 27 and 28 are provided with a'bottom, but with no sides, and it will be seen that, when forming the blocks, other parts are depended upon in connection with'the molds; while the molds form what might be called the bottom of the blocks, the

sides are formed'by plates presently to be described, and one end of the corner block is forine d'by a door, as will be explained.

' I employ an L-shaped pallet '29, conforming to the shape of plate 22', and having 111 's 30 extending outwardly frombn'e of its sides. adapted to traverse apertures 31 of Pallet 29 maybe readily position adjacent plate 2 and m y be removed'thereirom. It is intended that in operati'om one sideof the block will be formed by plate 23, this being true: whether it is a wall block or corner block. In order that the 'mold m y be firmly pr'e'ssed against plate 28, I employ wedges 32' pivotally secured upon links'33', the opposite ends of said; links being 'pivotally mounted at 3411 501 compression lev er 85,"thelatter being pivotally mounted, at 36 upon plate 22, i

A'rms"17 are recessed at 37 to receive wedges 32, and it will be understood that a swinging movement or lever 35 to the position shownin Figs. 17' or 19, will cause the wedges: to be .passedfoutavardly in recesses 37, these wedges contactingwith the ends of lugs 30 of pallet 29, which will cause said pallet to be moved to a'positi'on adjacent plate 22 said movement being in a direction toward plate 23L l vh'ile the blocks vary in length, they all. have an equal width, the

molds being also of equal width, and when wedges'32are' pressed outwardlyby means of lever 35, pallet 29 ism ov'ed inwardly to a contact with edge 0 ofthe mold 26, as shown in Fig. 17," and on account of this'inward movement'of'the pallet, theopposite edge (Z ofthe moldis pressed against plate 23. The contactwith edges 0 and cljust described of the meld, with plate 23 and with the pallet operates to retain the mold in a stationary position while'being filled, and by this ar rangeiiient'the mold, in conjunction with the pallet and plate form the bottom and sides of'a receptacle tocontain cement material for the formationof a building block.

In forming blocks 41', 42 and 43 usefof m olds 25, 26 and 28, respectively, the wall plate 22.' glaced in operative 38 (Figs. 7, 8, 10.) of the molds which forms the outer face 39 (Figs. 13, 14, 15.) of bonds 1'-0 of said blocks, rests upon plate 21, and in order to support the mold in a horizontal position, I use any convenient support, as block i l (Fig. 7.), this block being disposed contactingly between plate 21 and the lower surface of these molds.

In order to form the outer face of corner block 45, I construct door it; having hinges mounted as at 47 upon the frame. This door is provided with a. stop-lug IS secured upon its free end, adapted to make contact with one end of plate 22 (Fig. 1.) to limit the inward travel of the door when being closed; upon the outer face of plate I provide means for locking the door, as crank 4-5), and upon the outer face of the door is employed any convenient handle, shown at 50.

I construct the cover 51, pivotally mounted upon the frame as at 52 and having handle 5st, and also provided with stop-lugs 52", which extend outwardly from its tree end, said lugs being adapted to make contact with the upper edge of plate 22, at times hereafter named.

In operation, to form a corner block 45, mold 27 is employed; this mold has an outer wall (Fig. 9.) adapted to form the outer surface56 of bond 57 (Fig. 16.) of said corner block; this mold is placed in housingspace 2+l so that wall is disposml upon plate 21 5.), the terminal wall ot the mold passing below the plane of door 416. the opposite terminal of the mold extending above the plane of the cover, when the latter is closed. After the cover is thrown backward and the door has been closed, cement may be thrown upon the mold, lever 35 being first swung downward as shown in Figs. 19 and 20, The material is then agitated or t-amped so that the block will be perfectly formed; it will be understood that the bottom of the block thus formed will conform to the shape of mold 27, and that the transversely disposed end 59 of: the mold (Fig. 6).) will form one end of the block, door 46 "torming the opposite end of said block; pallet 29 and plate 23 will form the sides oi the block. Cover 51 is then closed, which forms the upper surface or face of the block. As thus formed, the portion indicated at c (Fig. in.) is the corner-bond, 57 is the wall-bond, and portion is formed between the planes of the lateral projections 7) oi. plates 22 and 23. After the corner block has been formed, cover 51 is thrown backward, lever 215 is moved to the vertical position shown in Fig. 1,which releases the pallet from its compressed position; door 46 is then opened and the mold is moved endwise so that terminal wall58 will make a clearance of vertical plate 23, after which arms 1.7 and the block are swung forwardOO degrees, so that plate 22' rests upon extensions 60 of supportingarms 2 and 3, lever 35 being used to produce this swinging movement of the arms and block. The block is then removed from plate 22 while resting upon the pallet, and the block remains upon the pallet until it becomes hardened in a suitable degree. In the formation of building blocks a large number of pallets are used.

In forming blocks of a limited length, as blocks 42 and 43 the pallet indicated at 61 (Fig. 23.) of rectangular form maybe used, this pallet being provided with lugs 31. The operation of forming blocks 41, 42 and 4:3 is the same as for forming the corner-block, except the mold, after formation of the block, is not moved endwise. As to the necessity of causing an endwise movement of the mold while forming a corner block, it should be remembered that the L-shaped plate 23 is stationary upon the frame, and is vertically disposed; the projection f of the corner block at this time occupies the space between the projection b of the pallet and a similar. projection of plate 23, and when arms 17 of the rock-levers, together with a corner block have the forward swinging movement, heretofore described, it is clear that the projection f must make a clearance of plate 23 during this swinging movement; for this reason only, and only while forming corner blocks, mold 27 must be moved endwise until wall 58 (Fig. 5.) passes horizontally beyond the plane of plate 23.

It will be seen, by reference to Figs. 11 and 12, that wall 62 may be constructed by use of blocks 41., 4:2, 43 and 45, said wall being composed of exterior and interior layers; that air-spaces 9 will be formed and that bonds 40 will overlap; also it will be seen that bonds 57'of the corner block will overlap bonds 40 of other wall blocks as shown; and

it will be appreciated that the layers of blocks forming the inner surface h of the wall do not extend to the exterior of the wall, the intention being to prevent moisture or frost from penetrating to the interior of the wall.

The parts thus described are few in number and the machine may be economically constructed; it is also considered durable, and by its use blocks for building purposes may be quickly formed, with a small outlay of labor.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is,

1. In a cement block machine, the combination with a supporting frame. having a stationary mold-side and provided with rock-levers having a pair of oppositely-dis posed arms adapted to have a transverse movement with reference to said stationary mold-side, of an apertured pallet-sustainingplate upon one of the oppositely-disposed arms of each of said rock-levers; a pallet disposed substantially parallel with and adjacent said apertured pallet-sustaining-plate and havinglugs adapted to have a seating within the apertures of said pallet-sustaining-plate; a molding-plate supported upon the other oppositely-disposed arm of each of said rock-levers and adapted to have a seating intermediate said stationary moldside and said pallet; means between one of the oppositely-disposed arms of each of said rock-levers and the lugs of said pallet to increase the adjacent distance between the apertured pallet sustaining plate and said pallet, and means to actuate said rock-levers to remove said molding-plate from a position intermediate said stationary molding-plate and said pallet.

, 2. In a cement block machine, the combination with a supporting frame having a stationary, L-shaped mold-side, and provided with rock-levers having a pair of oppositelydisposed arms adapted to have a transverse movement with reference to said stationary, L-shaped mold-side, of an apertured, L-shaped pallet-sustaining-plate upon one of the oppositely-disposed arms of each of said rock-' levers; an L-shaped, pallet disposed substantially parallel with and adjacent said apertured, L-shaped pallet-sustaining-plate and having lugs adapted to have a seating within the apertures of said L-shaped, pallet-sustaining plate; a moldingplate supported upon the other oppositely-disposed arm of each of said rock-levers and adapted tohave a seating intermediate said stationary, L- shaped mold-side and said L-shaped pallet; a swinging member upon the supportingframe adapted to make a closure with one of the ends of the molding-plate between a terminal of said stationary, L-shaped mold-side and a terminal of said L-shaped pallet; means between one of the oppositely-disposed arms of each of said rock-levers and the lugs of said L-shaped pallet to increase the adjacent distance between the apertured, L shaped pallet sustaining-plate and said L-shaped pallet, and means to actuate said rocklevers to remove said molding plate from a position intermediate said stationary, L-shaped mold-side and said L-shaped pallet.

In testimony whereof I have aflixed my signature in presence of two witnesses.
